Description:
Purpose: Handball goalkeepers are the last line of defense, and their abilities determine whether the ball is scored or saved. Positioning is one of the most important skills for a goalkeeper; proper positioning can maximize the blocking area between the shooter and the goal. However, due to a lack of resources and specialized knowledge among handball coaches, traditional positioning training often involves merely tracking the shooter's hand to simulate blocking routines, relying on subjective feedback from the coach. This approach is abstract and not effective for developing the necessary skills.Methodology: First, positioning training tools were designed using Micro:bit technology, infrared sensors, and AI posture detection from Scratch. This system consists of two tools: the "Shooter Handball Signal Transmitter" and the "Goalkeeper Sensor" When the shooter raises the sensor and presses the button, the goalkeeper, wearing the sensor, is required to move their trunk to point toward the shooter (signal transmitter). The goalkeeper's posture is detected by a Scratch, and their movement time and posture are displayed on Scratch each time. The tool was then used to compare movement times from different designated points for goalkeepers of varying levels: the Hong Kong Team, University Team, and Beginners. Additionally, interviews were conducted with handball goalkeeping coaches and handball coaches after testing the tools.Results: Analysis of nine goalkeepers revealed significant performance gradients: the average movement times for six designated positions were 2.46 seconds (Hong Kong Team), 2.62 seconds (University Team), and 3.08 seconds (Beginners), demonstrating the impact of competitive experience on positioning efficiency. Post-trial evaluations from 21 participants (goalkeepers and coaches) indicated that the average rating for the training tools across the criteria is approximately 7.67 out of 10
